HEIC to JPG on Windows Without Losing Quality

You plug an iPhone into a Windows PC, open the folder, and half the photos are `.heic` files that no viewer will open. Windows Photos, Paint and most older editors simply do not ship a HEIC decoder. This guide explains why that happens and the fastest ways to fix it — including a browser method that needs no installs.

Why Windows cannot open HEIC files

HEIC is a container based on HEIF, using HEVC video compression for still images. Apple adopted it because it stores the same visual quality at roughly half the size of JPEG. The catch: decoding it requires an HEVC licence, which Microsoft sells as a separate extension rather than bundling into Windows.

So the file is not corrupt and your photos are not lost. The operating system just lacks the codec.

Option 1: convert HEIC to JPG in the browser (no install)

1. 1Open the HEIC to PNG or Image Converter tool.
2. 2Drop the `.heic` file — it is processed on the server, not uploaded to a third party.
3. 3Choose JPG or PNG as the output and download the result.

This works on Windows, Linux, ChromeOS and Android, and it keeps the original EXIF orientation so portrait photos do not arrive sideways.

Option 2: install the HEVC extension

If you convert photos every day, installing the codec is worth it. Search the Microsoft Store for HEVC Video Extensions (there is a paid version and a device-manufacturer version). After installing, Windows Photos opens HEIC directly.

JPG or PNG — which should you pick?

• JPG — smaller files, fine for sharing and printing. Slight lossy compression on every save.
• PNG — lossless, larger, better when you will edit again or need transparency.
• WebP — best size-to-quality ratio for websites, but not every desktop app accepts it.

Does converting lose quality?

The decode step is lossless; the loss depends on the JPEG quality setting you choose. At quality 90 or above the difference is invisible at normal viewing sizes. If you need zero loss, choose PNG instead of JPG.

Batch converting a whole camera roll

Most people have hundreds of HEIC files, not one. Convert the folder in one pass with a desktop tool such as ImageMagick (`magick mogrify -format jpg *.heic`), or upload several files to the converter and download them as a ZIP.

Frequently asked questions

Is it safe to upload iPhone photos?

FilePlume processes uploads on its own servers and deletes them automatically after the job. No account is required for small files. If a photo is sensitive, use a local desktop converter instead.

Why is my converted photo rotated?

HEIC stores orientation in metadata. A converter that ignores EXIF will show portrait shots sideways. FilePlume applies EXIF orientation before saving, so the output matches what you saw on the phone.

Can I convert HEIC on Android?

Yes — the browser converter works the same way. Android 10 and later can also display HEIC natively, so conversion is mainly needed when sharing with Windows users.
